A control drive device for handle-driven lock body

Abstract

The invention discloses a control driving device for a handle-driven lock body, which comprises a base plate, a lock tongue, a pulling device, a lock cylinder device and a handle; The left and right sides of the pull device are respectively fixedly connected to the pull rod and the dead bolt in the pull device, and the handle and the lock cylinder device are respectively arranged on the bottom plate above and below the pull rod; the rack drag block in the pull device is movably connected to the pull rod, and the rack drag The moving block is connected to the handle through transmission; when the handle turns clockwise, the rack dragging block drives the unlocking slide in the lock cylinder device to move to the pull rod through the transmission device. Under the push of the lower part, one end extends into the dragging hole set by the rack dragging block, and the rack dragging block drives the pull rod to move and pull the bolt back to the lock body. The drive gear and the handle drive the gear to drive the movement of other components. Inserting the key into the lock cylinder only controls whether the lock cylinder controls the rotation of the shaft, so as to avoid the failure of the key broken in the lock cylinder.

Description

technical field [0001] The invention relates to a lock body, in particular to a handle-driven lock body. Background technique [0002] The lock body is one of the components of the lock. There are many kinds of lock bodies, the common ones are one-way lock body, three-way lock body, four-way lock body and so on. Generally used on anti-theft doors, it is responsible for the basic anti-theft work of the anti-theft door. The lock cylinder controls the operation of the lock body, and the lock body is responsible for opening and locking the doors and windows, and plays an important role in anti-theft. The current lock body can only be opened with a key outside the door, and after the door is used for a long time, the lock tongue and the door frame will generate large friction, as well as friction between the parts inside the lock body, and the size of the key is small and cannot withstand Larger torsional force may sometimes cause the failure of the key breaking in the lock cyli...
